Operating Instructions - BLUE ARROW CP120 S-FHSS RTB 2.4 GHz No. S2540
Trouble-shooting if the receiver LED flashes when switched on:
Possible causes
Binding failed
The throttle stick and throttle trim are set incorrectly
The transmitter batteries are flat
The flight battery is flat
Fault in transmitter or receiver
Solutions
Switch the radio control transmitter and receiver off. Now switch the transmitter on again, and connect
the receiver power supply.
Set the throttle stick and throttle trim to the lowest position (motor off), and repeat the
binding procedure.
Replace the flat batteries in the transmitter with new batteries, and repeat the binding procedure.
Give the flight battery a full charge, and repeat the binding procedure.
Replace the faulty unit with a new one, and repeat the binding procedure.
Please note:
1. It is essential to connect all the signal leads attached to the speed con-
troller correctly. If you neglect this, the speed controller could fail.
2. Use only the plastic screwdriver supplied in the set to adjust the pots, as
a metal tool could cause damage.
3. The model must stand on a level surface during the initialisation process.
4. Always switch the transmitter on first, and only then the receiver.
